been watching the thread for a bit and i think it's clear the issue isn't promotion threads but promo threads that lack substance beyond being a link dump and then the sheer volume of said link dump threads
limiting it so that only mods would be able to make threads for the category wouldn't make for a solution nor would shutting the whole thing down or whatever but it's be nice if there were more encouragement or better ways to ensure ppl arent making tons of the same thread
like with regards to "recently updated" type threads there's usually a "post your latest page/post your latest chapter" thread for comics and novels on a per month basis; the current one for january 2022 is here
if folks wanna get genre specific i don't think something like "share your stories with uncommon genre" would do too well (i mean maybe but eh....) but instead be specific to the genre of the story be it horror, historical, comedy, anthology or whatever. maybe toss in a why you chose that genre or something you're looking forward to doing within it (i.e. subversion of some kind or mashing up genres or twist stuff and so on)
also encouraging discussions so it's not just promo also works and imo tend to be a little more memorable in terms of thread types. I think a good one recently was the worldbuilding questions thread. honestly i think more like this could come into play as well maybe with discussion on how folks have developed the characters for their stories, what their alignments might be and why, i think someone did a facts related to your characters that arent story relevant.
There's absolutely ways to make interesting threads but people have to be making those threads (and getting enough engagements before the autoclose kicks in) but also not so much incentivizing participation in these threads (coz imo no one owes you a sub or sub back) but finding a way to show that these are better for promo than the usual link dumps
Not to mention I'm surprised how accepting of plain ol link dumps folks are because who doesn't want an excuse to go on and on about their characters or their story's worldbuilding. Like you don't have to post spoilers but giving a hint of what can be expected in your works or showing off some of the thought that's gone into it can be way more enticing at times than just a link and your blurb
personally with regards to the whole promo flood going on here i just stopped caring since it doesn't seem to be ending anytime soon and people are gonna o what they want. and as much as people try to show the available incentives to joining the discord i've personally joined but it feels way too busy for me (i prefer the small ones
). but like i think it's possible for stuff to change beyond implementation of stuff like "spam prevention" but it'll take time and community effort tho that alone depends on whose got the time and is willing to put in effort
